SACK CHUTE FOR HARVESTER THRASHERS.

Application led February The object of my invention is to provide animproved chute for delivering sacked grain for combinationharvester-thrashers in such manner that as the `machinery is movingthrough the field the thrashed grain as it is being discharged from thethrasher and sacked on a platform of the machine may be conveyedtherefrom in continuous groups to be conveniently loaded into wagons ortrucks and hauled t0 desired places of deposit.

In the accompanying drawings, forming part hereof, Figure 1 is a sideelevation of a thrasher element of a combination harvesterthrasher withmy improved sack chute associated therewith; Fig. 2 a front elevation;and Figs. 3 and il details of a portion of my improvement.

My invention is applied to the thrasher element, 5, of the combinationmachineand preferably used in connection with a platform. 6, extendingfrom the side of the thrasher at which the thrashed grain is deliveredthrough a sacher elevator or other wise, 7, into sacks, the open ends ofwhich sacks when filled with grain are sewed by an attendant on theplatform. 'Io said platform 6 I hinge or pivotally secure an inclinedchute 10 having guards, 1l, and a leg or legs, 12 adapted to rest upon asuitable support. as an arm, 18, extending from the axle or other partof the thrasher, and by which support and leg the lower end of the chutemay be n'iaintain-ed in the desired position in relation to the ground,while the swinging thereof in any desired vertical direction ispermitted through its hinged or pivotal connection to said platform 6,as stated. At the lower end of said chute I provide a tail-gate, 14e,which is preferably mounted upon and arranged to swing with arock-shaft, 15, and which attachment may be accomplished hy curving thelower end, 16, of said gate and riveting or otherwise securing the sameto said shaft 15, (indicated in Ilig. 1.-) which shaft terminates in alatch, 17, positioned at one side of said gate lei. said latch having abeveled end, 18, for a purpose to appear, the rock-shaft 15 beingmounted in bearings, 19, at each side of chute 1t). To said chute 10 Isecure an anchor, 21, to which is attached a spring, 22, which at its`opposite end at 23, is pivotally attached to said latch 17. Intermediatesaid anchor 2l and rock-shaft 15 I pivotally secure to the chute akeeper, 24, for limiting the move- 8, 1926. Serial No. 86,683.

ment of latch 17. On platform 6 or other suitable location I mount alever, 28, to which is secured a rodor rope, 29, extending to andattached to keeper 24.

In operation, it will be understood that the machine is' moving throughthe field cutting and thrashing grain, which grain is conveyed from thet-hrasher through the sacker elevator 7 and discharged into sacks,which, as. theyfare filled and sewed, are placed on the chute 10 and bygravity slide to the lower end thereof. As the lower sack reachestailgate 14 the attendantupon the platform by manipulating lever 28pulls keeper 24 olf latch 17, whereupon the lpressure of the sack as itmoves downwardly against said tailgate is sufficient to open said gateto the position indicated by dotted lines in F ig. 3, and passes outthereover to the ground, while the closely following oncoming sacks'maintain the gate in open position and follow the same course, the gatebeing limited in its downwardly inclined position by means'of stop 27,which checks the throw of latch 17. In the situation described spring22, secured to anchor 21 and pivotally connected to latch 7, follows thelatter in its upward movement through pressure of the sacks upontail-gate 14, as indicated by dotted lines in Fig. '3, and as a singleor the last sack of a group has passed through the gateway said springcontracts to normal condition, as shown in full lines in said Fig. 3, atthe same time pulling latch 17 downwardly and which increment is aidedby the inertia of the mo'ing parts, thus closqj said gate, and when thebeveled end of said latch contacts with keeper 2li it throws the latteraway from the latch so that said latch passes beneath the keeper, and byreason of tension spring 25 said keeper is returned to normal position,as indicated in Fig. fl, so that it lies across the latch to prevent thesame from displacement, and thus maintaining the tail-gate l1 in closedposition until the keeper is tripped through the rod 29 as described. Inthis manner I provide a chute which is sustained from the ground, andthe tail-gate of which is automatically opened by the action of themoving sacks. and closed by the devices described. rl`lie chute ishighly practical in connection with a traveling harvester-dirasher as Ihave dent- Aonstrated in actual practice in the fields, and theefficiency of which is increased for delivering sacked grain by thevibrations incident to 'the travel and operation oi' such machinery overground irregularities which arev resent in field operations; and by theemp oyment of a platform inthe manner stated an attenda'nt"'tlieron mayco'nveni; ently handle and sew such'vsacks and readily push or tumblethem onto the chute to be de'- posited on the ground.` I
